Unicode find/replace in regular expressions

[dsewell]

Using the "regular expression" option in oXygen 7.1 Find/Replace, I can find a character using Perl \uNNNN syntax, but I cannot use that syntax to replace. For example, to search for é (accented 'e', U+00e9) it works if I put

Code: Select all

\u00e9

in the "Text to find" field, but if I want to replace the character with è, U+00e8, it does not work to put

Code: Select all

\u00e8

in the "Replace with" field. Instead, the replacement is literal 'u00e8'.

Is this a bug, or am I misunderstanding how Perl regex syntax works?

(I realize that I can use an XML numeric character entity as a workaround, or for that matter I can just input the UTF-8 character from my keyboard, but I have some use cases where it would be more convenient to use \u syntax.)

Actually, I guess that \uXXXX syntax is from Java rather than Perl--I still don't understand why it works in "find" but not "replace".

Hello David,

Currently Unicode characters are not supported as \uNNNN expressions in the Replace field. We will consider supporting them in a future version. You have to use the character directly, that is the character é. If you set a Unicode font capable of rendering the needed character in Options -> Preferences -> Fonts -> Text components you can see the character rendered correctly in the Replace field.

Sorin

Thanks for the clarification,
